# Industrial Specification: Feed Box

## 1. Technical Definition
A component of shale shakers that receives and distributes drilling fluid onto the screening surface.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-3.5 bar inlet pressure, 0.1-0.8 bar distribution pressure**. Failure boundary: **Structural failure at 5.2 bar internal pressure, hydraulic failure at 0.05 bar distribution pressure**, Mechanism: **Yield strength exceedance at 345 MPa von Mises stress (ASTM A36 steel), fluid starvation causing uneven distribution**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Abrasive particle accumulation exceeding 45% volume fraction | 8 | Flow restriction causing 70% pressure drop across distribution channels | Integrated 316L stainless steel wear plates with 2.5 mm thickness, 45° flow deflection angles |
| Corrosion from chloride concentration exceeding 5000 ppm in drilling fluid | 8 | Pitting corrosion at 0.8 mm/year penetration rate in weld zones | Cathodic protection with -850 mV potential, epoxy-phenolic coating with 250 μm DFT |

- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are used in manufacturing feed boxes for shale shakers?
**A**: Feed boxes are typically constructed from carbon steel, stainless steel, or abrasion-resistant steel to withstand harsh drilling environments and abrasive drilling fluids.

### Q: How does a feed box improve shale shaker performance?
**A**: The feed box evenly distributes drilling fluid across the screening surface, preventing localized overloading and ensuring optimal solids separation efficiency.

### Q: What are the key components of a feed box assembly?
**A**: Key components include the inlet flange for fluid entry, distribution baffles for even flow, outlet weir for controlled discharge, and mounting brackets for secure installation on shale shakers.
